For me, it was months jobless and isolated at a parent's house in the middle of nowhere.
For others, not battling means not getting out of bed, and for people facing other "demons" (what a bad word) not fighting might mean to continue to consume drugs or alcohol, or to keep not eating, or eating too much.
For me, it goes "I'm feeling depressed. Okay, I feel depressed. That's interesting. Now what is it that I must do right now at this moment? Get out of bed. Okay, done. I'm still depressed, but what's next?"
In other words, I don't bother fighting it or avoiding it. I just acknowledge it and then figure what needs to be done next.
To me, that is fighting.
Could be this is a cultural problem. In our culture we’re supposed to like work and everybody is expected to shut up.
